How Are Leg Ulcers Diagnosed

Leg ulcers – Diagnosis and treatment of leg ulcers

A vascular specialist a healthcare provider specializing in the circulatory system and knowledgeable about wound care can examine the ulcer. Your provider will examine your skin and the wound.

Referral To A Specialist

In some cases, your GP or nurse may decide to refer you to a specialist in conditions affecting the blood vessels .

For example, you may be referred to a vascular specialist if your GP or nurse is unsure about your diagnosis, or if they suspect your ulcer may be caused by artery diseases, diabetes or rheumatoid arthritis.

After taking your medical history and examining you, the vascular specialist may need to arrange further investigations to plan your treatment.

Causes Of Venous Ulcers

Venous ulcers most often form around the ankles.

Venous ulcers typically occur because of damage to the valves inside the leg veins. These valves control the blood pressure inside the veins. They allow it to drop when you walk. If the blood pressure inside your leg veins doesn’t fall as you’re walking, the condition is called sustained venous hypertension. That increase in blood pressure causes ulcers to form on your ankles.

Venous ulcers may also be caused by other problems with your leg veins. These include:

  • Varicose veins. These are large, bulging leg veins. They occur when valves in the leg veins dont work well, allowing blood to collect in the lower leg.

  • Chronic venous insufficiency. Like varicose veins, this condition occurs when your leg veins cant pump blood back up to your heart. Blood then pools in your lower legs, causing your legs to swell. Since the blood can’t flow well in your legs, the swelling may be extreme. This extreme swelling can put so much pressure on your skin that venous ulcers form.

  • Assess the brand:Does it operate with integrity and adhere to industry best practices?

What is stasis dermatitis?

Stasis dermatitis is skin inflammation that develops in people with poor circulation. It most often occurs in the lower legs because thats where blood typically collects.

When blood collects or pools in the veins of your lower legs, the pressure on the veins increases. The increased pressure damages your capillaries, which are very small blood vessels. This allows proteins to leak into your tissues. This leakage leads to a buildup of blood cells, fluid, and proteins, and that buildup causes your legs to swell. This swelling is called peripheral edema.

People with stasis dermatitis usually experience swollen legs and feet, open sores, or itchy and reddish skin.

The symptoms of stasis dermatitis include:

  • skin discoloration

You may also experience symptoms of venous insufficiency, including:

  • calf tenderness
  • a dull ache or heaviness in your legs that gets worse when you stand

In the early stages of stasis dermatitis, the skin on your legs may look thin. Your skin may also itch, but try not to scratch it. Scratching can cause the skin to crack and fluid to seep out.

Signs And Causes Of Venous Ulcers

Leg Ulcers

Venous ulcers are non-healing or slow-healing wounds that form as a result of blood pooling in the legs and feet. This happens when the walls or valves in the veins of the lower extremities dont work effectively. This is called venous insufficiency.

Venous ulcers are more common in women and older people. Several factors increase your risk of developing venous ulcers, including:

  • Long periods of immobility, such as bed rest

What Are The Treatments For Poor Leg Circulation

Poor leg circulation is a common problem, especially as we age. Fortunately, there are simple habits and lifestyle changes you can make to reduce pain associated with poor circulation in legs. While its important to consult with your doctor, here are some ways you can improve circulation in your legs at home:

What Are Foot Ulcers

A foot ulcer is an open sore on the foot.

A foot ulcer can be a shallow red crater that involves only the surface skin. A foot ulcer also can be very deep. A deep foot ulcer may be a crater that extends through the full thickness of the skin. It may involve tendons, bones and other deep structures.

People with diabetes and people with poor circulation are more likely to develop foot ulcers. It can be difficult to heal a foot ulcer. In people with these conditions, even a small foot ulcer can become infected if it does not heal quickly.

If an infection occurs in an ulcer and is not treated right away, it can develop into:

  • A spreading infection of the skin and underlying fat
  • A bone infection
  • Gangrene. Gangrene is an area of dead, darkened body tissue caused by poor blood flow.

Among people with diabetes, most severe foot infections that ultimately require some part of the toe, foot or lower leg to be amputated start as a foot ulcer.

Foot ulcers are especially common in people who have one or more of the following health problems:

  • Peripheral neuropathy. This is nerve damage in the feet or lower legs. Diabetes is the most common cause of peripheral neuropathy. When nerves in the feet are damaged, they can no longer warn about pain or discomfort. When this happens, tight-fitting shoes can trigger a foot ulcer by rubbing on a part of the foot that has become numb.

In addition to diabetes, other medical conditions that increase the risk of foot ulcers include:

Are Other Venous Ulcer Treatments Available

Venous ulcers that are severe or not responding to standard therapies may require additional treatments such as:

  • Growth factor therapy, injectable substances that attract healthy cells to ulcers.
  • Hyperbaric oxygen therapy, a treatment in which you sit in a special, pressurized chamber and inhale pure oxygen.
  • Lymphedema therapy, massage, skin care and bandaging techniques that clear fluid buildup.
  • Skin graft, replacing diseased skin with healthy skin from another part of your body.
  • Stem cell therapy, injections of bone marrow to generate healthy tissue.
  • Venous disease treatment to correct blood pooling problems and improve circulation.
  • varicose veins in the leg.

Manage Your Blood Sugar Levels

Do varicose veins cause leg ulcers? Can leg ulcers be treated?

One of the most important things you can do to treat diabetic ulcers is to keep your blood sugar levels under control by monitoring them on a regular basis.

You can also help treat and prevent high blood sugar levels by following a healthy diet, exercising regularly, and taking any medication prescribed by your doctor.

Chronic Leg Ulcers: Epidemiology Aetiopathogenesis And Management

Shubhangi Vinayak AgaleAcademic Editor: Received

Abstract

Chronic leg ulcer is defined as a defect in the skin below the level of knee persisting for more than six weeks and shows no tendency to heal after three or more months. Chronic ulceration of the lower legs is a relatively common condition amongst adults, one that causes pain and social distress. The condition affects 1% of the adult population and 3.6% of people older than 65 years. Leg ulcers are debilitating and greatly reduce patients’ quality of life. The common causes are venous disease, arterial disease, and neuropathy. Less common causes are metabolic disorders, hematological disorders, and infective diseases. As many factors lead to chronic lower leg ulceration, an interdisciplinary approach to the systematic assessment of the patient is required, in order to ascertain the pathogenesis, definitive diagnosis, and optimal treatment. A correct diagnosis is essential to avoid inappropriate treatment that may cause deterioration of the wound, delay wound healing, or harm the patient. The researchers are inventing newer modalities of treatments for patients with chronic leg ulceration, so that they can have better quality life and reduction in personal financial burden.

Medical History And Examination

Your GP or practice nurse will ask whether you have any other symptoms associated with venous leg ulcers, such as:

  • swelling in your ankles
  • discoloured or hard skin

They’ll try to determine the cause of the ulcer by asking about underlying conditions or previous injuries, such as:

Diagnosis Of Leg Ulcers

  • examine the wound
  • perform some tests to measure the blood flow in your lower leg, such as the ankle-brachial index. This test compares blood pressure readings taken at the ankle and at the arm using a device called a Doppler machine
  • recommend an angiogram for an arterial ulcer, to find out if the artery needs surgery to clear the blockage.

What Causes Leg Ulcers

Venous Ulcer Treatment in Chennai

Causes of leg ulcers include:

  • Chronic venous insufficiency: Chronic venous insufficiency occurs when faulty valves in leg veins allow blood to flow backward into the leg where it pools. If you develop high blood pressure in the leg veins, tiny blood vessels can burst, causing inflammation, itching and dry skin. Leg ulcers develop when the skin breaks open.
  • Diabetes: High blood sugar levels from diabetes can cause fat deposits to form inside blood vessels, causing them to narrow. Reduced blood flow can cause nerve damage or diabetic neuropathy. With these nerve problems, you may not be able to feel a leg ulcer or know its there. Diabetes also slows the wound healing process.
  • Peripheral artery disease : This condition causes plaque to build up in the arteries . The blood vessels in the leg become narrow, leading to poor blood circulation. The reduced blood flow slows the healing of leg ulcers. People with diabetes are more likely to develop PAD.
  • High blood pressure: Chronic, poorly controlled high blood pressure can cause an extremely painful ulcer on the lower leg called a Martorell ulcer. High blood pressure causes the capillaries in the skin to become narrow, cutting off the blood supply to the skin. The skin can die, forming a leg ulcer.

What Are The Symptoms

Skin ulcers look like round, open sores. They range in severity and are usually minor injuries on the skin.

In severe cases, ulcers can become deep wounds that extend through muscle tissue, leaving bones and joints exposed.

The symptoms of skin ulcers include:

  • discoloration of the skin

People can develop the following types of skin ulcer:

Cleaning And Dressing The Ulcer

The first step is to remove any debris or dead tissue from the ulcer and apply an appropriate dressing. This provides the best conditions for the ulcer to heal.

A simple, non-sticky dressing will be used to dress your ulcer. This usually needs to be changed once a week. Many people find they can manage cleaning and dressing their own ulcer under the supervision of a nurse.

What Is Poor Leg Circulation

Poor leg circulation, or peripheral artery disease , is a circulatory problem in which narrowed arteries reduce blood flow to your limbs. While it commonly occurs in the legs, peripheral artery disease can also affect the peripheral arteries to the stomach, arms, and head. The arteries harden due to plaque buildup in the arteries and blood vessels, and this blocks the normal blood flow through the vessels and results in poor circulation in the legs.

While it isnt a condition in itself, poor leg circulation may be a sign of larger health issues. If youre experiencing the associated symptoms of poor blood circulation, its important to consult with your doctor, who can check for other health complications that may worsen over time. These can include obesity, diabetes, high blood pressure or cholesterol, and various heart and arterial conditions.

Arterial & Venous Ulcers

Skin ulcers are wounds that develop on your skin due to poor circulation of blood. When blood flow is blocked, the overlying skin and tissues dont receive oxygen. This damages the tissue and causes the area to form an open wound.

There are different types of ulcers:

  • Arterial ulcers. These occur when you have artery disease, such as peripheral artery disease , and are usually on your feet and toes. These are less common than venous ulcers.
  • Diabetic foot ulcers. Diabetes can cause nerve damage, which can lead to a loss of feeling in your feet. This can result in unnoticed sores that can become serious foot ulcers.
  • Venous ulcers. These are caused by damaged valves in your lower-leg veins, which disrupt normal blood flow and allow blood to flow backward. The abnormal blood flow causes the veins to get overfilled, and fluid seeps out into the surrounding tissues.

Foods Rich In Omega 3s

Omega 3s are known to promote blood circulation and increase circulation.

Fatty Fish

Salmon and mackerel provide a tremendous dose of omega-3 fatty acids. Omega 3 fats promote the release of nitric acid, which works to dilate blood vessels and improve blood flow. They also reduce the risk of blood clots by preventing blood platelets from clumping.
